Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed March 23,1905. Serial No, 251,635.

To all whmn it may concern.-

Be it known that I, THOMAS HADDEN, a citizen of the United States,residing at Ferguson, in the county of Logan and State of Kentucky,haveinvented certain new and useful Improvements in Vises, of which thefollowing is a specification.

My invention relates to improvements in Vises; and one object of theinvention is the provision of a vise which can be operated with ease andwhich will exert great pressure in clamping an object and which willhave means for cutting a pipe, bar, or strip of metal as circumstancesrequire.

Another object of my invention is the provision of a vise which may beused with ease in an upright or horizontal position and which willinstantly grasp the object, which is capable of various adjustments tosuit requirements, and which will be of durable, inexpensive, andpractical construction.

With these objects in view my invention consists of a vise or clampembodying novel features of construction and combination of parts,substantially as disclosed herein.

Figure 1 represents a perspective view of a vise or clamp constructed inaccordance with and embodying my invention. Fig. 2 represents a centrallongitudinal sectional view, and Fig. 3 represents a detail sectionalview of the jaws provided with cutters.

My vise or clamp is of extremely simple construction and comprises thestationary jaw A, to which is secured the pair of plates B, in which ispivoted at O the movable jaw D, between the jaws being placed the springE, and the pair of plates are provided with extended portions B,provided with a series of open.- ings B to receive the fulcrum or pivotF of the cam-head G, having the lever H. This cam-head is provided witha bore or passage J, through which passes the rod K, whose upper end isconnected at L to the pivoted angular hand-lever M and whose lower endis formed with a tooth or point N for engaging the rack O on the pivotedjaw, and a spring P surrounds the rod and bears against the flange Q onsaid rod and the wall R of the camhead.

From the foregoing description, taken in connection with the drawings,the operation of my vise will be readily understood, and it is evidentthat when the lever, with cam-head, is operated the cam engages thepivoted jaw and forces the jaws against the object and the spring-rodengages the rack and holds the jaws upon the object with a strong grip,and to cut a strip of metal I employ the pair of cutters or knives S,which fit in recesses T of the jaws, the lever-cam bringing the cuttersupon the object and cutting the object with asmooth clean cut, as isevident.

It will be observed that the fulcrum or pivot of the lever-cam may bechanged to any one of the series of openings in the plates according tothe pressure to be applied; also that the vise may be used in ahorizontal or vertical position and that it will perform its functionsin an eflicient and practical manner.

I claim- 1. A vise or clamp, consisting of a pair of clamping-jaws, arack carried by one of said jaws, a lever-cam engaging one of the jaws,and means for retaining said lever-cam consisting of a spring-actuatedrod arranged in the cam of the lever and adapted to engage the rack.

2. A vise or clamp consisting of a pair of jaws, a rack carried by oneof said jaws, alevercam and a rod carried by the lever and having aconcealed spring for forcing said rod into engagement with said rack forsecuring the jaws in the adjusted position.

3. A vise or clamp consisting of a stationary jaw, a pair of platescarried by said jaw, a pivoted jaw mounted in said plates, a rackcarried by the pivoted jaw, a lever-cam adjustably fulorumed in saidplate, a springactuated rod arranged within said cam, and a pivotedhandle-lever connected to said rod for disengaging it from the rack ofthe pivoted jaw.

4:. A vise or clamp consisting of a pair of jaws provided with knives orcutters, a levercam engaging one of the jaws, a rack carried by the jawengaged by said cam, and a rod passing through said cam and engaging therack for securing the jaws in adjusted position.

5. A vise or clamp, consisting of a pair of pivoted jaws, a pair ofplates secured to one of the jaws and provided with a series ofopenings, a lever having a cam adapted to be fulcrumed in any of theseries of said openings, a rack on one of the jaws, and aspring-actuated rod carried by the cam and engaging the rack to retainthe lever.

In testimony whereof I affix my signature in presence of two witnesses.
